AUGER FOR BORING EARTH.

To all whom 'it may concern Be it known that we, ASHLEY CRAFTS andEBENEZER VEEKS, of Auburn, in the county of Geauga and State of Ohio,have invented a new and useful improvement in augers for boring holesthrough various strata of the earth without the use of a cylindricaltube, such as is used by Page, Disbrow, and others, which improvement isdescribed as follows, reference being had to the annexed drawings of thesame, making part of this specification.

Figure l, is a side elevation of the auger. Fig. 2, is a view of thelower end, inverted. Fig. 3 is a vertical section.

Similar letters in the different figuresl refer to corresponding parts.

This auger differs from all others for boring holes in the earth inbeing made externally in the form of a frustum of a cone and entirelyopen at the lower end and with a spiral lip B or.inclined shelf combinedwith the spiral thread A and connected to the lower edge thereof andnearly at right angles thereto, and extending the whole length of thethread, having no central shaft below the upper end of the spiralthread; by which construction this auger will bore holes in the ground,whether it be sandy, stony, or clayey, of the same diameter as its lowerend, by causing the earth and gravel to be packed solidly in the frustumof a cone space inclosed by the spiral thread A so that it can be raisedand withdrawn from the hole without crumblingthe said spiral shaft orlip B formed around the lower edge of the spiral thread packing theearth in the auger and preventing its descent before the auger iswithdrawn from the hole to be emptied or cleared and by having the saidlo'wer and larger end of t-he auger entirely open stones of a diameternearly equal to the diameter'of the bore of said open end may bereceived and discharged freely. The friction is likewise reduced by theconical shape of the auger to the lower end thereof, which is in contactwith the sides of the hole being bored, while the threads of the smallerdiameter are relieved from friction by not touching the sides of thehole thus bored. The stem, shank, or shaft C of this auger co-mmenceswhere the twist or spiral terminates and rises in a straight line ashigh as intended, where an eye is formed to receive the handle D bywhich it is turned, formed like the shank and eye of a common twistauger. In boring with this auger the core of earth is not cut up andbroken into small particles as experienced in the use of Page andDisbrows boring tools, but it cuts the piece of earth out whole andpacks it into the concavity of the auger by the spiral lip or inclinedplane shelf B formed on the lower edge of the spiral thread A, whichacts against the said core and gradually lifts it as it is separatedfrom its bed.

le do not claim to be the original inventers of an auger for boring inthe earth, but,

l/Vhat we do claim as our invention and improvement and desire to secureby Letters Patent 1srIhe peculiar construction of the auger asaforesaid, namely, the combination of the In testimony whereof ,we havehereunto signed our names before two subscribing witnesses.
